John McCall 424cec97bd Change QualType::getTypePtr() to return a const pointer, then change a
thousand other things which were (generally inadvertantly) relying on that.

Douglas Gregor 45e84b0053 NetBSD, OpenBSD, and Dragonfly BSD also have arc4random. Patch from
Joerg Sonnenberger!

Douglas Gregor cdbc539aee Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr,
that captures the substitution of a non-type template argument pack
for a non-type template parameter pack within a pack expansion that
cannot be fully expanded. This follows the approach taken by
SubstTemplateTypeParmPackType.

Ted Kremenek 8cb349de80 Cleanup confused code that redundantly called "getDeclContext()" twice.
Found by clang static analyzer.

llvm-svn: 123459
2011-01-14 20:34:10 +00:00
Ted Kremenek 95d874fa5d Teach RegionStore::EnterStackFrame() to handle
the case where the called function has fewer
formal arguments than actual arguments.  This
fixes a crash in the analyzer when doing
function call inlining.

Ted Kremenek f224820b45 Remove warning in dead stores checker for
dead stores within nested assignments.  I have
never seen an actual bug found by this specific
warning, and it can lead to many false positives.

Zhongxing Xu 3a3c0fd2d1 CXXBaseObjectRegion is like FieldRegion. Need to blast through it when
getting the base region. This makes the RemoveDeadBindings() correct.

llvm-svn: 123375
2011-01-13 12:46:31 +00:00
Zhongxing Xu 0d87e0c65b Support inlining base initializers. We still haven't got it completely right,
since the bindings are purged after they are set up. Need to investigate
RemoveDeadBindings algorithm.

Ted Kremenek 304b6e4aa1 Fix a corner case in RegionStore where we assign
a struct value to a symbolic index into array.
RegionStore can't actually reason about this,
so we were getting bogus warnings about loading
uninitialized values from the array.  The solution
is invalidate the entire array when we cannot
represent the binding explicitly.

Fixes <rdar://problem/8848957>

Ted Kremenek f41bdd7c24 Rename 'HasGeneratedNode' to 'hasGeneratedNode'
and 'getBasePredecessor()' to 'getPredecessor()'.

Also remove a unneeded save-and-restore of
node builder's tag field.

Ted Kremenek f044bd68e1 Remove CheckerContext's dependence on setting
the node builder's "tag" ivar (which we would
like to remove).

2011-01-12 07:20:03 +00:00
Argyrios Kyrtzidis 4b7433fab2 [analyzer] Introduce ObjCSelfInitChecker, which checks initialization methods to verify that they assign 'self' to the
result of an initialization call (e.g. [super init], or [self initWith..]) before using any instance variable or
returning 'self'.

Ted Kremenek a00bccc0c5 Rework ExprEngine::processCFGBlockEntrance()
to use a node builder.  This paves the way
for Checkers to interpose (via a "visit" method)
at the entrance to blocks.

Zhongxing Xu 0710f5c5e1 The isPrefix() checking is redundant. Lvalue incremental/decremental expressions
are all prefixes.

Alexis Hunt 1d7926502f Renamed CXXBaseOrMemberInitializer to CXXCtorInitializer. This is both shorter,
more accurate, and makes it make sense for it to hold a delegating constructor
call.

Douglas Gregor 35c7e84eb7 There is nothing interesting to analyze with a sizeof...(pack) expression
llvm-svn: 122818
2011-01-04 18:46:34 +00:00
Douglas Gregor e8e9dd624c Implement support for pack expansions whose pattern is a non-type
template argument (described by an expression, of course). For
example:

  template<int...> struct int_tuple { };

  template<int ...Values>
  struct square {
    typedef int_tuple<(Values*Values)...> type;
  };

It also lays the foundation for pack expansions in an initializer-list.

Ted Kremenek 5614c46fcf Add basic support for pointer arithmetic in
SimpleSValBuilder.  This clears up some
false positives emitted by ArrayBoundCheckerV2
due to the lack of support for pointer arithmetic.

2010-12-24 06:19:58 +00:00
Ted Kremenek d99bd55a5e Chris Lattner has strong opinions about directory
layout.  :)

Rename the 'EntoSA' directories to 'StaticAnalyzer'.

Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).
